Fuck them, you know who they are and what they do. long story short, they hack like noneother, then they get banned, then bitch like little pussys complaining and spamming threads saying things like "Y DID YOU BAN ME? I BOUGHT NX AND I WAS GOING TO SPEND IT! I DONT HACK!1 OMFG". And shit like that. Fuck you. you need to burn in the deepest depths of hell, then dig a deeper hole and crawl in it. They get a ban lifted, bitch asking why they got banned, then they get permabanned. *create new account* bitch even more. Need I say more?
If you look around here and Nexon forums, they are everywhere. Beware. They are lurking.
